Which Component of a Phospholipid is Found in the Interior

Question

Which component of a phospholipid is found in the interior of a lipid bilayer?
A)glycerol
B)fatty acids
C)phosphate group

Accepted Answer

The fatty acids are hydrophobic and tend to associate with each other in the interior of the lipid bilayer, creating a hydrophobic barrier. The glycerol and phosphate group form the hydrophilic head of the phospholipid, which interacts with the water on the surface of the bilayer.
